In an effort to better understand bitcoins, I thought I would give my take on what a bitcoin is and why it has value. You can then tell me if and why I am wrong.
First, bitcoins are a commodity designed to have the features we want in a money. Without transactions and human interaction, it is worthless. Without the monetary functions bitcoin has, it is worthless. The function of bitcoins is what drives demand, and it is supply and demand which determine price. It is the function of this new currency where it derives it's real value. To argue that bitcoins have no value because they aren't backed by anything is like trying to argue that gold has no value because it is not backed by anything. One hundred years ago gold is what was used to back the currency, it was the commodity underlying the paper. Bitcoins is the digital commodity which will back a future currency.
Second, the theoretical max of 21 million bitcoins is arbitrary because bitcoins are infinitely divisible and it is a commodity. You could just as easily have a theoretical limit of 1 bitcoin with an initial disbursement of 0.00000238 BTC and nothing would change at all.
Those are two rough ideas which I haven't found much validation with. Thoughts?
Why it has value for me...
1. It isn't backed by anything, which i find as a huge plus. Because if it was backed by something it wouldn't be as efficient of a currency, for these 2 reasons:
a) it would require a safe deposit of gold that is secure, this would substantially increase the transaction costs and make it less efficient as money.
b) everytime new coins are minted someone would have to purchase that commodity that backs it and transport it to that safe deposit.
In all such backing not only would increase costs and make it less efficient as cash, but it would also require me to trust a central authority. Needless to say i have no plans to invest in gold when i hold a currency, if i wanted gold i'd buy gold directly.
2. No central authority, no refunds, no chargebacks, no counterfeit, and therefore extremely low transaction costs. As perfect as cash could be.
3. Limited and exponentially shrinking supply of new coins, the number is irrelevant whats relevant is the formula it makes it easy for me to expect what the money is or will be worth when i know the supply will be fixed.
